What is the role of apomorphine in Parkinson’s treatment?
Apomorphine is a dopamine agonist used in the treatment of Parkinson’s disease (PD), particularly for the management of motor symptoms and relieving patients experiencing “off” periods or motor fluctuations. It’s typically prescribed when oral medications (like levodopa) are no longer providing steady relief or when late-stage PD symptoms need more immediate relief.
Role of Apomorphine in the Treatment of Parkinson’s Disease
Rescue Therapy for “Off” Episodes
Apomorphine is also referred to as a “rescue therapy” because it provides rapid relief from motor symptoms, particularly when patients experience the “off” periods (when levodopa’s effects wear off prior to the next dose).
It is generally held back for acute relief, restoring motor function within 10-20 minutes of receiving it, and is of great value in emergency situations when the patient cannot wait for their next planned dose of oral medication.
Injection or Infusion
Apomorphine is either injected as a subcutaneous injection or administered as a continuous infusion through a small pump for sustained relief over a duration of time.
The infusion method is typically reserved for those who need frequent dosing or more extended symptom control.
Alternative to Oral Medications
Apomorphine can be given when oral levodopa alone no longer provides stable symptom control.
It can be introduced into a regimen of levodopa and other PD drugs in order to improve motor function and reduce motor fluctuations.
How Apomorphine Works
Apomorphine acts on the dopamine receptors in the brain, particularly those areas that control movement. It produces the same action as dopamine by stimulating the receptors, restoring dopamine activity in the brain.
Unlike levodopa, which needs to be converted into dopamine by the body, apomorphine has a direct effect on dopamine receptors and does not need to be converted.
Apomorphine Efficacy
Apomorphine can be extremely effective at improving motor symptoms during periods of “off,” such as:
Bradykinesia (slowness of movement)
Rigidity
Tremors
It has been shown to produce dramatic improvement in motor function, and most patients achieve quicker and more consistent symptom control compared to oral medications alone.
Side Effects of Apomorphine
While effective, apomorphine is not without side effects, some of which are more problematic due to the rapid action of the drug:
Nausea and Vomiting: Extremely common side effect. This can be managed by anti-nausea medication (e.g., domperidone) when administered concurrently with apomorphine.
Drowsiness and Sleepiness: Sleepiness can be profound, especially on commencement of therapy or when doses are adjusted.
Hypotension (Low Blood Pressure): Apomorphine may cause orthostatic hypotension (sudden drop in blood pressure when standing up), causing dizziness, fainting, or falling.
Involuntary Movements (Dyskinesia): Involuntary movements may emerge in some patients as a result of apomorphine therapy.
Injection Site Reactions: Redness, swelling, or irritation at the injection site may appear.
Psychiatric Effects: Hallucinations, confusion, or changes in mood may infrequently occur, especially in elderly patients.
Administration of Apomorphine
Subcutaneous Injection: Apomorphine is administered into the fatty tissue layer under the skin (usually in the thigh or abdomen). This provides quick relief within 10 to 20 minutes.
Continuous Infusion: For patients who require frequent, ongoing relief, apomorphine may be administered via a small infusion pump, which is set to provide a continuous dose throughout the day.
Patients typically take apomorphine with the assistance of a trained clinical practitioner in order to teach proper administration and to monitor side effects and effectiveness.
Apomorphine Versus Other Parkinson’s Medications
Levodopa remains the cornerstone of PD management, but motor fluctuations (e.g., “wearing-off” periods) can make apomorphine a worthwhile addition for most patients.
Dopamine agonists (e.g., pramipexole or ropinirole) are also used to manage symptoms, but apomorphine acts more rapidly and is generally saved for advanced PD stages or as a short-term solution for breakthrough symptoms.
Conclusion
Apomorphine is also used as a powerful rescue medication in the treatment of Parkinson’s disease, having a rapid impact on motor symptoms during “off” periods. It can be a useful choice when oral medication no longer provides stable symptom control. Due to its side effects, however, it’s often left for supervised use and when other medications are less effective.

Management of drug-related motor fluctuations in Parkinson’s disease (PD) represents a significant challenge for clinicians. Motor fluctuations develop with more severe disease, particularly after long-term treatment with levodopa, the most commonly used drug. Motor fluctuations can occur in two ways as separate phenomena:
“On” and “Off” Periods:
“On” time: When the medication is effective, and the patient experiences improved motor function (i.e., movement is improved, tremor is reduced, etc.).
“Off” time: When the medication effect has dissipated and there is a return of symptoms such as tremor, rigidity, and slowness of movement.
Dyskinesia (Involuntary Movements):
Dyskinesia is a frequent side effect after long-term levodopa treatment. It is an involuntary jerky movement that typically happens at the time when the drug is exerting its peak activity level.
Treatment Approaches to Medication-Related Motor Fluctuations:
1. Optimizing Levodopa Therapy:
Adjusting Dosage and Timing: The adjustment of the dose and frequency of levodopa can control the occurrence of motor fluctuations. Clinicians may prescribe smaller and more frequent doses of levodopa to maintain more stable blood levels and reduce “off” periods.
Controlled-Release Formulations: Taking extended-release (ER) or controlled-release formulations of levodopa can extend the duration of action and reduce the frequency of motor fluctuations.
Combination Medications: Some medications combine levodopa with other drugs (e.g., carbidopa/entacapone/levodopa combinations) to prolong the effect of levodopa and manage fluctuations. The addition of entacapone (a COMT inhibitor) can be used to provide steady dopamine levels and minimize “off” times.
2. Dopamine Agonists:
Adjunctive Therapy: Dopamine agonists (e.g., pramipexole, ropinirole) mimic dopamine and can be used to manage motor fluctuations by producing more continuous dopamine stimulation, reducing the use of levodopa alone.
Use Early in Disease: These drugs are typically used earlier in the course of Parkinson’s and can delay the need for levodopa, perhaps reducing the risk of motor fluctuations and dyskinesia.
Side Effects Management: Dopamine agonists can lead to impulse control disorders, sleep attacks, or somnolence as side effects, and their use must therefore be carefully monitored.
3. Amantadine for Dyskinesia:
Reducing Dyskinesia: Amantadine, an antiviral drug, is regularly used to manage dyskinesia in patients with long-term levodopa treatment. It can reduce involuntary movement by modulating the release of dopamine and inhibiting glutamate in the brain.
Timing and Dosing: Amantadine can be titrated based on the severity of dyskinesia but should be monitored closely for adverse effects of livedo reticularis (skin rash) or edema.
4. MAO-B Inhibitors:
Prolonging Levodopa Action: MAO-B inhibitors (e.g., rasagiline, selegiline) inhibit the enzyme that breaks down dopamine, thereby making more dopamine available in the brain. When used with levodopa, they can reduce “off” times and enhance motor function.
Considerations: These are widely used as adjuncts to levodopa, particularly in early to mid-stage Parkinson’s, and can help provide smoother motor control.
5. COMT Inhibitors:
Entacapone and Tolcapone: COMT inhibitors entacapone and tolcapone can be added to levodopa therapy to increase its duration of action and reduce motor fluctuations, particularly “off” times. These drugs inhibit the enzyme catechol-O-methyltransferase that breaks down levodopa, thus prolonging its duration of action.
Tolcapone Use: Tolcapone is effective but requires regular monitoring of liver function due to its liver toxicity.
6. Deep Brain Stimulation (DBS):
Surgical Option: For those patients who experience severe motor fluctuations that are not well managed with medication, deep brain stimulation (DBS) may be an option. This is a surgical procedure where a device is implanted that sends electrical pulses to parts of the brain that are involved in movement (e.g., the subthalamic nucleus or globus pallidus).
Benefits: DBS can reduce “off” time, improve motor function, and reduce the need for high doses of levodopa. However, it is generally only considered in those with severe Parkinson’s and requires strict assessment.
7. Dietary and Lifestyle Changes:
Protein and Levodopa Absorption: Motor fluctuations can be managed with dietary modifications. Protein can slow down levodopa absorption, and therefore, patients are sometimes requested to take levodopa 30-60 minutes prior to a meal or postpone meal times to allow maximum efficacy of the drug.
Regular Exercise and Physiotherapy: Exercise maintains motor function and reduces rigidity. Physiotherapists and occupational therapists also provide individual exercises to improve movement and balance to reduce the impact of fluctuations.
8. Patient and Family Education:
Symptom Tracking: A medication diary to note “on” and “off” times helps clinicians to adjust treatment. A consciousness of the effects of medication on daily activities improves patient outcomes.
Education on Medication Adjustments: Teach patients and their families about medication timing and side effects, especially how “on” and “off” periods happen.
Individualized Treatment Approach:
Management of medication-related motor fluctuations in Parkinson’s disease is individualized because patients may respond differently to treatment options. Clinicians will typically take into account:
Disease stage
Symptom severity
Side effect profiles
Patient preferences (e.g., medications’ tolerability)
As Parkinson’s is so complicated and response to treatment is so variable, regular follow-ups and multidisciplinary care (including neurologists, physiotherapists, and occupational therapists) are also important in adjusting medication and managing fluctuations effectively.
